I served as a consultant, guiding the complete redesign and optimization of their parking and electric vehicle charging IoT systems — from the hardware level to system monitoring and management.

This is a passion project that is currently in it's initial stage, drawing upon the expertise I've accumulated during my years of experience in the parking industry.

Initially conceived as a straightforward visualization project, it evolved into something more substantial.

The most noteworthy achievement in the project was discovering an efficient way to count and sum the sizes of a thousand terabytes of small files. We were able to reduce the processing time from 2 days with standard Unix tools to just 4 hours with my solution.

I re-engaged with the project once more, but this time in the capacity of a contractor.

During this period, my focus was solely on IoT, embedded and all it's related components and aspects.

We were in the process of creating new products, including a comprehensive ticket kiosk system.

Together with a colleague from Rollet, we started to develop a sensor platform.

Our primary focus was on agricultural monitoring, which required us to design sensors that could operate on solar energy and transmit data to a central unit from distances spanning hundreds of meters.

Through the use of periodic deep sleep cycles and LoRa technology, we achieved our goal successfully.

When I joined Rollet as a full-stack developer, the company was still in it's early stages as a startup.

Over the course of my time there, I handled a wide array of development tasks, spanning from user interface system design to developing IoT components. Later my main area of concentration shifted to IoT development and monitoring.

I was responsible for the development of the company's internal HR system, which served as my initial job in the field.

It proved to be a valuable experience as I primarily worked autonomously on the technical aspects while also contributing to the product development.
